The Sponsor referred to raw clinical data requested in the previous tcon on May 31, with the clinical team and stated that according to the guidance and pre BLA meeting, they need not submit any data. The clinical reviewer pointed out that according to the guidance data is not required for CMC section of the application and to prove efficacy, but was necessary to prove safety of the product. This point was reiterated in the pre BLA meeting in July 2010, and is captured in the meeting minutes. FDA also stated they need the raw data to verify the tables and figures in Section 5.4 of their submission.
The Sponsor stated that they plan to delete confidential information such as recipient names from the spreadsheet before they submit to their file. FDA stated it was acceptable to delete patient names, but all of the other information in the dataset had to match exactly what was in their records.
